I went though the design and made little improvements. Mostly I added a wire guide path though the robots chassis plates and a way to screw down the middle deck. I then also raised the lower deck supports to make more room to get to the toggle switch. 

I re-printed all the parts and then reassembled the robot with the modifications. The middle deck with the battery tie down Velcro was the coolest add to this build and overall the robot looks much cleaner and refined. 

I had a idea on how I could steal him away from the kid and put him to work in the lab as well. I was thinking well I could add a flashing yellow latching button on a rod facing up in the air and have a electro magnet on the bottom. I could then "activate" him and he would do a little search pattern and pick up all the screws or metal bits I dropped.
